A Fly On The Wall That Can Save Your Life. Lento, The Award-Winning Smoke Detector From Jalo.

Lento is an unexpectedly whimsical but safe and effective photoelectric smoke alarm designed by Finnish designer Paola Suhonen for Jalo Helsinki.

Lento will not only enhance the safety of your home, but you will also add a touch of originality. Forget the boring and unattractive smoke alarms on the market – with Lento an essential everyday object such as a smoke alarm will become an original piece of design for decorating your home and keeping it safe. Installing Lento will take only a few seconds thanks to its 3M tape and there will be no need for screws or a power drill.

The whole surface of the smoke alarm acts as a test button, so there are no tiny push buttons, but the whole external casing acts as a press switch for silencing false alarms and testing the performance. Lento has been developed and manufactured according to the requirements and standards for smoke alarms. Lento is lightweight and has a 5 year battery life time.
